SIFT Practice Questions (2026) — Free Sample Questions with Answers

Answer: B

Regular hexagon: The figure contains only 45° and 90° angles and has no six-sided outline, so a hexagon cannot be traced.

Right triangle: Correct. Each diagonal cuts the square into two right (isosceles) triangles, and the two diagonals together form four smaller ones.

Equilateral triangle: An equilateral triangle needs 60° angles. The angles in this figure are only 45° and 90°.

Circle: The figure is made entirely of straight lines, so no curve can be traced.

On Hidden Figures, check the angles and line directions in the complex figure first; a shape whose angles aren't present can't be hidden there.

Answer: D

The helicopter climbs straight up: Climbing is done mainly by raising the collective, not by moving the cyclic forward.

The nose yaws to the right: Yaw is controlled with the anti-torque pedals.

The main rotor RPM increases: Rotor RPM is governed by power (throttle or governor) and collective loading, not by cyclic position.

The rotor disk tilts forward and the helicopter begins to move forward: Correct. Forward cyclic tilts the rotor disk forward, tilting the total rotor thrust forward and accelerating the helicopter in that direction.

The helicopter moves in the direction the rotor disk tilts, and the cyclic controls that tilt.

Answer: B

Level flight, banked left, flying along the coast with water on the right: In a left bank the horizon appears higher on the left. Here it is higher on the right.

Level flight, banked right, flying along the coast with water on the right: Correct. Horizon through the center = level pitch, horizon higher on the right = right bank (the right wing is down, so more ground fills the right side), and the coast runs ahead with water to the right.

Climbing, banked right, flying along the coast with water on the left: The horizon is centered, so the aircraft is not climbing, and the water is on the right.

Level flight, banked right, flying directly toward the shore: The coastline runs straight ahead, so the aircraft is flying parallel to it, not across it.

The horizon tilts opposite to the bank: in a right bank it appears higher on the right side of the windshield, just as on an attitude indicator.

Answer: A

Brownout is a hazardous loss of visibility that crews manage through planning, crew coordination and go-around decisions.: Correct. The passage defines brownout, explains why it is dangerous, and lists how crews prepare for it, which this option covers in full.

Helicopters should never land in dusty terrain.: The passage says the problem cannot always be avoided and describes how to manage it, not avoid it entirely.

Brownout occurs only at high altitude.: The passage ties brownout to dry, dusty terrain and rotor downwash. Altitude is never mentioned.

Crew members are more important than pilots during landings.: Crew callouts are one technique the passage lists. It does not rank the importance of crew members.

A good main-idea answer covers both the problem and the response described in the passage, with no extreme or added claims.

Answer: D

The same as the original price: The 20% decrease is taken from a larger base (120%), so it removes more than the increase added.

4% higher than the original price: The direction is wrong. The net effect is a decrease.

20% lower than the original price: This ignores the first increase completely.

4% lower than the original price: Correct. 1.20 x 0.80 = 0.96, so the final price is 96% of the original, a 4% decrease.

For successive percent changes, multiply the factors (1 + r1)(1 + r2). Equal up and down percentages always give a net loss.

Answer: B

60 rpm counterclockwise: The speed is right, but A to B reverses direction and B to C reverses it again, so C turns clockwise like A.

60 rpm clockwise: Correct. The idler B does not change the overall ratio: 90 x 10/15 = 60 rpm. Two reversals return C to A's clockwise direction.

30 rpm clockwise: 30 rpm is gear B's speed (90 x 10/30). Gear C has fewer teeth than B and turns faster.

135 rpm clockwise: This uses the ratio upside down (90 x 15/10). C has more teeth than A, so it turns slower than A.

In a simple gear train, only the first and last gears set the speed ratio (idlers cancel out). Every mesh reverses direction, so an odd number of gears means the last gear turns the same way as the first.
